KNEADER FOR DOUGH-KNEADING MACHINES.

SPEGIFIGA'IION forming part of Letters Patent No. 683,390, datedSeptember 24, 1901.

Application tiled March 5, 1901.

.To @ZZ whom, t may concern,.-

Be it known that I, OsKAR DRoscHTz, a subject of the King of Saxony,residing at Schlossstrasse 3, Bautzen, in the Kingdom of Saxony andEmpire of Germany, have invented certain new and useful Improvements inKneaders for Dough-Kneading Machines, of which the following is aspecification.

My invention relates to a kneader for dough kneading machines. Thiskneader consists of a Z-shaped rotary agitator whose middle bar formsacute angles with t-he two arms carrying knives.

In the annexed drawings, Figure 1 is a side elevation, partly insection, showing the arrangement of the agitator in a kneading-machine;and Fig. 2 is a side elevation showing the agitator to an enlargedscale.

The agitator a b c d e is substantially 2- shaped, its middle bar cforming an acute angle with the two adjoining arms ZJ d. Owing to thisshape of the agitator the thorough working of the material is insured.As the corner formed by the bar c and the adjoining arm b corresponds inposition to the middle of the arm d, and the corner formed by the bar cand the adjoining arm d corresponds in position to the middle of the armb, these corners in the rotation of the agitator will pass into anddivide the strips of dough which are formed by one-half of the bar c,the arm d, and the arm e, connected with a journal f, and by the otherhalfof the bar c, the arm Z), and the arm a, likewise connected with ajournal f.

Serial No. 49,88% (No model.)

In order to facilitate the passage of the agi# tator through the doughto produce the strip,

the edges of the agitator which first penetrate into the dough aresharpened. As shown by the transverse sections in Fig. 2, the outeredges of the arms a b and d e constitute cutting edges, while theconnecting-bar c has a cutting edge in the middle. By knives 7i, whichare fastened to the arms Z7 and d and are inclined thereto and whosefaces form angles with the plane passing through the agitator, the doughwill likewise be divided 'and will be moved in the direction of the axisof the trough g, wherein the agitator works.

At both its ends the kneader is suitably supported in slides 7c forenabling it to be easily removed from the trough.

What I claim as my invention, and desire to secure by Letters Patent,is-

A kneader for dough-kneading machines, comprising a Z-shaped rotaryagitator whose middle bar' forms an acute angle with the adjoining armswhich carry knives inclined thereto and having faces inclined to theplane of the kneader.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
